This can be used in countless ways, and unlike Classic Pesto it can be made year-round because of the availability of parsley. We like this best on sandwiches and panini. The variation with
tasty capers with turkey or pork, in particular.
Wash and pat the parsley leaves dry. Peel and trim the garlic.
Put the parsley, garlic, walnuts, salt, and pepper in a food
processor and process until finely chopped. With the motor running, pour the olive oil through the feed tube into the machine in a slow stream, and blend to a smooth emulsion.
Transfer the pesto to a serving bowl. Keeps, covered, in a container in the refrigerator for 1 week.
